调试 Helidon MP 应用程序
Debug Helidon MP Application
我是 Helidon MP 的新手,我正在尝试实现我的第一个微服务。
我无法找到如何调试我的应用程序,有人可以给我指出一个很好的示例或文档吗?有没有办法在调试模式或类似模式下启动运行时?
提前致谢
Helidon MP 在作为应用程序服务器的意义上并不是真正的运行时。它主要是您添加到项目中的库的集合。因此,您可以像调试任何其他 Java 应用程序一样调试使用 Helidon 的程序,即通过向命令行添加 Java 调试开关。
这是 java -agentlib:jdwp=help
的输出,应该可以帮助您开始基本的 Java 调试:
$ $(/usr/libexec/java_home -v11)/bin/java -agentlib:jdwp=help
Java Debugger JDWP Agent Library
--------------------------------
(see http://java.sun.com/products/jpda for more information)
jdwp usage: java -agentlib:jdwp=[help]|[<option>=<value>, ...]
Option Name and Value Description Default
--------------------- ----------- -------
suspend=y|n wait on startup? y
transport=<name> transport spec none
address=<listen/attach address> transport spec ""
server=y|n listen for debugger? n
launch=<command line> run debugger on event none
onthrow=<exception name> debug on throw none
onuncaught=y|n debug on any uncaught? n
timeout=<timeout value> for listen/attach in milliseconds n
mutf8=y|n output modified utf-8 n
quiet=y|n control over terminal messages n
Obsolete Options
----------------
strict=y|n
stdalloc=y|n
Examples
--------
- Using sockets connect to a debugger at a specific address:
java -agentlib:jdwp=transport=dt_socket,address=localhost:8000 ...
- Using sockets listen for a debugger to attach:
java -agentlib:jdwp=transport=dt_socket,server=y,suspend=y ...
Notes
-----
- A timeout value of 0 (the default) is no timeout.
Warnings
--------
- The older -Xrunjdwp interface can still be used, but will be removed in
a future release, for example:
java -Xdebug -Xrunjdwp:[help]|[<option>=<value>, ...]
